VAPORIZER FOR COLD VAPORS OR THE LIKE.

SPECIFICATION forming part of Letters Patent No. 708,647, dated September 9, 1902.

Application filed May 17, 1901.

To all whom it may concern.-

of the Emperor of Germany, residing at WiI- mersdorf, Germany, have invented certain new and useful Improvements in Vaporizers for Cold Vapors or the Like, of which the following is a specification.

This invention relates to a new arrangement of vaporizing apparatus which is chiefly intended for cold vapors, "its object being to utilize the heat of the heating mediumin a plain or uniform apparatus or cylinder as far as possible and until the vapors obtained are superheated.

The essential feature of the present invention is that thevaporizing-chamber, which is traversed by a series of small horizontallyarranged tubes and in which the counter-current principle is employed, is provided in or toward its lower half with one or more horizontal partitions, so that the fluid in the evaporator is in a cooler state in the lower layers; whereas a temperature corresponding to the pressure of the condenser is obtained in the upper part, the vapors being,.in fact, moist in the lower layers, dry in the middle, and superheated in the upper. This division can be effected by means of any insulating-walls rendered adjustable, if so desired.

Upon the annexed drawings the new vaporizer is shown in one form by way of example.

Figure 1 is a longitudinal sectional elevation, and Fig. 2 is a cross-section.

The cylinder at is closed at the ends by the tube-platesbb, through which the heatingtubes 0 are passed and suitably secured, so that the interior of the tubes communicates with the chambers d, which are formed by attachmentsor covers e e at the two ends. Into one of these chambers 01 the heating medium, such as exhaust-steam from a steamengine or the like, is admitted in order that it may pass through the tubes 0 and in a direction contrary to that in which the fluid to be heated traverses the chamber a. This is insured by a suitable number of partitions i in the chambers d d, which determine the path for the heating medium.

The fluid to be vaporized-sulfurous acid, ammonia, and the likeflows into the actual vaporizing-chamber a from below at a. This Serial No. 60,645. (No model.)

chamber, however, does not form an uninterrupted space in which a change of temperature would be quickly effected, but is provided near its bottom with a horizontal partition f,'which allows communication only 9 may be arranged in the upper part of the chamber beneath the upper row of the tubes in order to prevent the immediate or a toosudden change or to retard it. Under certain circumstances the separation by means of the very small tubes or a series of horizontal tubes suffices for the purpose. The level .of the fluid to be vaporized should be so regulated that the uppermost tubes traversed by the entering-that is, the hotteststeam should pass through the vapor-space, so that they can superheat the vapor. The superheated vapor collects in the upper part of the chamber a and in the dome h, whence it is conveyed to'its working cylinder. In this way the difierencc of temperature, which otherwise must amount to about 10 centigradc between the heat of the exhaust-steam and the boiling-point of the fluid to be vaporized, can be utilized to within about 2.

Having described my invention, what I claim,'and desire to secure byLetters Patent, 1s

1. A vaporizer, comprising a chamber or casing provided with an inlet and an outlet, heating-tubes extending through said chamber, and a partition located in the chamber between the inlet and the outlet, to retard the flow oi the fluid through the chamber. i

2. A vaporizer, comprising a chamber or casing provided with an inlet and an outlet, heating-tubes extending through said chamber, and a partition located in the chamber between the inlet and the outlet and extending lengthwise of said tubes, to divide the said chamber into a preheating-compartment and a vaporizing-compartment.

3. A vaporizer, comprising a chamber or casing provided with an inlet and an outlet, heating-tubes extending through said chamber, a partition located in the chamber between the inlet and the outlet, to divide said chamber into a preheating-compartment and a vaporizing-compartment, and a perforated partition located between the first-named partition and the outlet, whereby a superheating-compartment will be formed adjacent to :0 the outlet.
